Spreading of cooperative behaviour across interdependent groups
Luo-Luo Jiang, Matjaz Perc
Recent empirical research has shown that links between groups reinforce individuals within groups to adopt cooperative behaviour. Moreover, links between networks may induce cascad…
A stochastic approach to the harmonic map heat flow on manifolds with time-dependent Riemannian metric
Hongxin Guo, Robert Philipowski, Anton Thalmaier
We first prove stochastic representation formulae for space-time harmonic mappings defined on manifolds with evolving Riemannian metric. We then apply these formulae to derive Liou…
Toroidal Lie superalgebras and free field representations
Naihuan Jing, Chongbin Xu
A loop-algebraic presentation is given for toroidal Lie superalgebras of classical types. Based on the loop superalgebra presentation free field realizations of toroidal Lie supera…
An entropy formula for the heat equation on manifolds with time-dependent metric, application to ancient solutions
Hongxin Guo, Robert Philipowski, Anton Thalmaier
We introduce a new entropy functional for nonnegative solutions of the heat equation on a manifold with time-dependent Riemannian metric. Under certain integral assumptions, we sho…
Martingales on manifolds with time-dependent connection
Hongxin Guo, Robert Philipowski, Anton Thalmaier
We define martingales on manifolds with time-dependent connection, extending in this way the theory of stochastic processes on manifolds with time-changing geometry initiated by Ar…
If cooperation is likely punish mildly: Insights from economic experiments based on the snowdrift game
Luo-Luo Jiang, Matjaz Perc, Attila Szolnoki
Punishment may deter antisocial behavior. Yet to punish is costly, and the costs often do not offset the gains that are due to elevated levels of cooperation. However, the effectiv…
